The BIND Configuration Files

In IRIX, the named database files are stored in the /var/named directory. A README file contains a short summary of the setup procedure and a list of official names for BIND clients and servers. Typically, servers are also clients. BIND clients require the /etc/resolv.conf file.

The /var/named/Examples subdirectory contains sample named database files. The files in the Examples directory should be used and changed to reflect your setup. These files use the record format described in Appendix A, "BIND Standard Resource Record Format." The database files needed to set up your BIND environment are:

• named.boot

• root.cache

• named.hosts

• named.rev

• localhost.rev

Note: If your network has more than one domain, incorporate the domain name as part of the named.hosts, named.rev, and localhosts.rev filenames when you create your versions of these files. The number and configuration of the database files depend on the server type.

Table 6-2 summarizes which database files are required for each type of server.
